didn't

didn't 是 did not 的缩略形式，用来否定过去发生的动作或状态。

💡 记忆钩子

把 didn't 想成给过去时动作按下“否定开关”：它先表示“过去没有”，后面再接动词原形，说明某件事没有发生。

📝 学习建议

重点先掌握“didn't + 动词原形”这一结构，不要在 didn't 后面再使用过去式。
didn't 否定的是过去时；不要把它误解成一般现在时的否定形式，后者通常用 don't 或 doesn't。

📖 中文释义

verb

core 过去没有

📖 表示过去没有做某事，或过去并不是某种情况；didn't 本身承担过去时和否定作用，后面的动词要用原形。

💡 常用句型是“主语 + didn't + 动词原形”，例如 didn't go、didn't know。它是日常英语中很常见的缩略形式；在正式写作或需要强调时可以改用 did not。不要说 didn't went 或 didn't knew，因为过去时已经由 did 表示。

I didn't see your message yesterday.

我昨天没有看到你的消息。

She didn't bring her umbrella.

她没有带伞。
